Abstract: 194,691. Marks, E. C. R., (Cleveland Metal Products Co.). Feb. 28, 1923. Wick burners, annular; wickoperating devices; flame spreaders. -In a wick burner oi the kind described in Specification 206,545 in which the air distributing member or flame spreader is engaged and moved by the wick during its initial upward movement, this movement brings into action mechanism operative during the further movement of the wick within its burning range to move the flame spreader so as to bear either a constant spaced relation to the wick or to be at a variable distance from the wick, which variable distance may be adjustable according to the atmospheric &c. conditions. The burner shown comprises inner and outer wick tubes 1, 2 enclosing a tubular wick 5 attached to a carrier 7. The burner is supported by a member 26 attached to the stove base and an elbow fitting 27 forming the fuel supply connection. The inner wick tube is formed with an offset part 10 which is closed at the bottom and top by walls 11, 12. The wick is operated by means of a hand-wheel 23 on a spindle 22 which is journaled in a bracket 25 depending from the burner and carries a pinion 21 engaging a rack-member 18. The member 18 is attached to a rod 15 connected by a member 16 to the carrier 7. As the wick rises it engages the flange 53 of a flame spreader 50 which is attached to a post 45 rigidly secured to a spanplate 30 to which a depending frame 31 is attached. The lower end of the frame 31 is guided by bent-over portions 32, 33 of the bracket 25 and carries on a pivot 36 a member 35 formed with an integral resilient pawl 39. The upward movement of the flame spreader carries the pawl into engagement with a ratchet wheel 60 in the spindle 22 the movement of the member 35 being maintained vertically by a wall 62 on the bentover portion 33 of the bracket 25. Owing to the wheel 60 being of greater diameter than the pinion 21, the flame spreader is then raised more rapidly than the wick until it is properly positioned in respect to the wick. The member 35 is then swung by the wheel 60 laterally over the top of the wall 62. The lower end of the member 35 is formed as a cam surface and is slightly eccentric in respect to the pivot 36. The top of the wall 62 is bent angularly to provide a bearing for the cam surface. The upward movement of the wick is arrested by the engagement of a stop 65 on the member 35 with the frame 31. The flame-spreader 50 is removably secured to the post 45 by means of a gravity-actuated latch-member 47 pivoted in the bifurcated end of the post. The spreader may be lifted off the post by means of a movable collar 55 which as it is raised engages an extension 57 on the latch plate and retracts the keeper portion 51. In order to adapt the burner to different grades of oils and varied atmospheric &c. conditions the pawlcarrying member may be fitted with a pivoted cam plate 70, Fig. 8, which may be adjusted to vary the profile of the cam surface. The plate 70 is secured in its adjusted position by means of a screw 73 extending through registering crossing slots in the plate and member.
